About this study

Official title: Artificial Intelligence (AI)-Assisted Risk-based Prostate Cancer Detection: A Synergy of Novel Biomarkers, Advanced Imaging, and Robotic-assisted Diagnosis

This is a prospective clinical study recruiting 510 men at risk of PCa to undergo urine, blood, AI-assisted ultrasound and AI-assisted MRI investigations to stratify risk of clinically significant PCa (csPCa). (sample size calculation in section 5)

Read the detailed description

All recruited patients will undergo investigations including urine for spermine, blood for miRNA, TRUS, and MRI prostate. Patients with high suspicion of csPCa in any one step (urine, blood, ultrasound, OR MRI) will be offered an image-guided prostate biopsy. This will be followed by machine learning techniques to find the best combination in predicting csPCa.

    Measured: Through study completion, an average of 1 year

Secondary outcomes (4)

  1. Diagnosis of any grade of prostate cancer

    Assessed by prostate biopsy

    Measured: Through study completion, an average of 1 year

  2. Proportion of men with diagnosis of clinically insignificant prostate cancer

    Assessed by prostate biopsy

    Measured: Through study completion, an average of 1 year

  3. Prostate biopsies that can be avoided

    Assessed by using different machine learning algorithms

    Measured: Through study completion, an average of 1 year

  4. The concordance of AI-assisted TRUS & MRI diagnosis and biopsy outcomes

    Assessed by using different machine learning algorithms and prostate biopsy result

    Measured: Through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by Chinese University of Hong Kong at 1 site in Hong Kong.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Peter Ka-Fung CHIU, FRCS, PhD (35052625, peterchiu@surgery.cuhk.edu.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Diagnosis of clinically significant Prostate cancer (csPCa); • csPCa is diagnosis of ISUP Grade group ≥2 prostate cancer in at least 1 biopsy core (time frame: Through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05443412, which also lists 24 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2025.
